Description

Technical Field

[0001] This utility model relates to a magnetic shielding barrel, and more particularly to a magnetic shielding barrel made of flexible coils that is applied in the field of shielding barrel technology. Background Technology

[0002] A magnetically shielded container is a device used to shield or reduce magnetic field interference. They are typically made of materials with high magnetic permeability, such as iron, nickel, or their alloys, which guide magnetic field lines, thereby reducing the impact of external magnetic fields on the interior space of the container. Magnetically shielded containers are widely used in applications requiring reduced electromagnetic interference, such as in laboratories, medical equipment, precision instruments, and electronic equipment.

[0003] Chinese invention patent CN202111617254.4 discloses a "Consistency Detection Device for Atomic Magnetometer Gas Chambers", which includes a magnetic shielding barrel, which is set outside multiple atomic gas chambers and is used to shield external magnetic interference; and a coil magnetizing device, which is set outside multiple atomic gas chambers and is used to compensate for the magnetic field environment inside the magnetic shielding barrel.

[0004] Traditional magnetic shielding barrels use coil windings to generate the magnetic field. The coil windings are made by winding a long wire. However, this coil winding method is relatively complex, which increases the difficulty of manufacturing the shielding barrel. In addition, the magnetic compensation device made by coil windings is not easy to replace and cannot adjust the required magnetic field capacity according to experimental needs. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the existing coil winding method is relatively complex, which increases the difficulty of manufacturing and processing the shielding barrel, and the magnetic compensation device made by coil winding is not easy to replace and cannot adjust the required magnetic field capability according to experimental needs.

[0006] To address the aforementioned problems, this utility model provides a magnetic shielding barrel made of flexible coils, comprising a barrel body, an inner layered shielding sleeve inside the barrel body, an inner liner tube fixedly fitted inside the inner layered shielding sleeve, coil patches attached to the inner wall of the inner liner tube, the coil patches being arranged in a spiral shape, and end plates fixedly connected to both ends of the coil patches, with sliding joints fixedly connected to the bottom of the end plates, a support shaft fitted inside the inner liner tube, two sliding joints being slidably connected to both ends of the support shaft, and assembly grooves opened at the top of both ends of the inner liner tube, with locking sleeves inserted into the assembly grooves, and two locking sleeves being screwed to both ends of the support shaft.

[0007] In the magnetic shielding barrel made of flexible coil described above, the coil patch is spirally attached to the inner wall of the inner liner tube, and is slid on the support shaft through the sliding joint. The distance between the two end terminal plates of the coil patch is adjusted to make the coil patch more closely attached to the inner wall of the inner liner tube, thereby effectively improving the uniformity of the generated magnetic field.

[0008] As a further improvement of the present application, the coil patch is made of a flexible circuit board, and the edge of the coil patch is fixedly connected with an elastic rib made of elastic plastic. The elasticity of the elastic rib enhances the toughness of the coil patch, effectively improves the spiral deformation ability of the coil patch, and facilitates the attachment of the coil patch to the inner wall of the inner liner tube.

[0009] As a further improvement of the present application, the middle part of the two ends of the support shaft is rotatably connected with an adjusting bolt, and the adjusting bolt is threadedly connected with the sliding joint. By rotating the adjusting bolt and using the thread connection between the adjusting bolt and the sliding joint, the sliding of the sliding joint on the support shaft is adjusted.

[0010] As a further improvement of the present application, the bottom of the support shaft is fixedly connected with a placement tube, the placement tube is coaxially sleeved with the inner liner tube, and the outer surface of the placement tube corresponds to the inner surface of the coil patch. The elastic rib is spirally wound on the outer surface of the placement tube. By adding the placement tube, the magnetic field experiment is carried out in the placement tube, which effectively avoids direct contact with the coil patch during the experiment, thereby effectively protecting the coil patch. When the coil patch is taken out, the coil patch is wound on the outer surface of the placement tube, which facilitates the safe taking out of the coil patch.

[0011] As another improvement of the present application, a rotating groove is formed in the outer surface of the placement tube, a rotating shaft is rotatably connected in the rotating groove, and the rotating shaft is adhesively connected with the inner surface of the coil patch. By adhesively connecting the rotating shaft with the coil patch, the stability of the coil patch wound on the placement tube is effectively improved, which facilitates the stable storage of the coil patch.

[0012] As a further improvement of the present application, one half of the outer surface of the rotating shaft is fixedly embedded with a magic hook piece, and the surface of the elastic rib is fixedly embedded with a magic hair piece. The magic hook piece and the magic hair piece are adhesively connected. By rotating the outer surface of the rotating shaft with the magic hook piece, the magic hook piece and the magic hair piece are adhesively connected to realize the adhesion of the rotating shaft and the coil patch.

[0013] In summary, this invention uses a coil patch that is spirally attached to the inner wall of the liner tube to arrange a magnetic field coil inside the liner tube. Compared with the existing coil winding method, this is simpler and more conducive to the production and processing of the magnetic field coil. Furthermore, the attached coil patch is easy to disassemble and replace, allowing for independent adjustment of the required coil patch according to experimental needs. By sliding the sliding joint on the support shaft, the distance between the end plates at both ends of the coil patch can be adjusted to achieve the outward bulging and contraction of the spiral coil patch. When the coil patch bulges outward, it makes it fit more closely to the inner wall of the liner tube, effectively improving the uniformity of magnetic field generation. When the coil patch contracts, it makes it easier for the coil patch to move away from the inner wall of the liner tube, facilitating the removal of the coil patch. Attached Figure Description
